Generator

When the engine is started, the following sequence of events occurs:

• Generator (GEN) (10346) begins to generate alternating current (AC).
• Alternating current (AC) is converted to direct current (DC) by the rectifier (10304).
• Current is supplied through the vehicle's system through the output stud located on the rear of the generator.
• Generator output current is determined by the voltage at the A circuit (battery sense voltage).
• The circuit voltage is compared to a set voltage internal to the voltage regulator (VR) (10316).
• Voltage regulator controls the generator field current to maintain proper generator output.
• Set voltage will vary with temperature.
• Set voltage is typically higher in the winter.
• Set voltage is typically lower in the summer.
• Varying set voltage allows for better battery recharge in the winter.
• Varying set voltage reduces the chance of overcharging the battery (10655) in the summer.
